This is especially true when you want to watch a movie collection stored on your hard drive or share a presentation with colleagues.
There are several proven methods for this task, from built-in operating system functions to specialized software. Wireless connection Provides freedom of movement and eliminates the need to purchase long HDMI cables. In this article, we'll cover the basic methods guaranteed to work with current TV models.
To get started, make sure your computer and TV are connected to the same network. Wi-FiThis is a fundamental requirement for all the methods described below, as data transfer occurs locally through the router. If the devices are on different subnets, detection will be impossible.
Using the built-in Connect to a Wireless Display feature in Windows
Windows 10 and Windows 11 operating systems have native support for the technology. Miracast, which allows you to duplicate your screen without installing additional software. TVs Samsung support this standard out of the box, so this method is the easiest for most users.
To start broadcasting, press the following key combination on your computer keyboard: Win + KA "Connection" panel will appear on the right side of the screen, where the system will begin searching for available devices. Find your TV's name in the list. Samsung and click on it to pair.
A connection confirmation request may appear on the TV screen, which you will need to confirm with the remote control. Dual Sense or a standard Samsung remote. Once successfully connected, your desktop image will be copied to the big screen. You can work in any program, and everything will be visible on the TV.
⚠️ Note: When using Miracast, image quality may vary depending on the wireless network congestion. For viewing 4K video, we recommend using a wired connection or DLNA methods.
It's important to understand the difference between these modes. You can either duplicate your screen or extend it, using your TV as a second monitor. This is convenient for multitasking, when you're working on your PC while watching a movie on your TV.
DLNA technology and the standard Media Viewer application
If your goal is to play video files, and not duplicate the desktop, then the technology DLNA It's perfect. It allows you to stream media directly, without burdening your computer's processor with rendering the entire interface.
To start playback, find the desired video file on your computer, right-click it, and select "Cast to Device." Select your TV from the list that appears. SamsungThe video will open in the standard Windows player and begin streaming to your TV.
This method is advantageous because playback controls (pause, rewind) are controlled from the computer, while the TV simply displays the image. The image quality remains intact, without the compression typical of some streaming apps.
However, there's a caveat with file formats. The built-in Windows player may not support some rare codecs that the TV itself can handle without any problem. In such cases, it's better to use specialized media servers.
Samsung Smart View app for advanced control
Company Samsung developed my own application Smart View (formerly known as PC on TV), which provides deep integration between your PC and TV. It allows you to not only mirror your screen but also manage content through a user-friendly interface.
The app is available for download in the Microsoft Store. Once installed and launched, it automatically detects TVs on the network. The interface is divided into sections: a screen preview, a file list, and settings. You can drag and drop photos and videos directly into the app window for instant viewing.
One of the key features is the ability to use your smartphone as a remote control for playback on your PC. This creates a unified ecosystem where all devices are synchronized. Multi-View It even allows you to split the TV screen into parts.
⚠️ Please note: The Smart View app interface and functionality may vary depending on your Windows operating system version and TV model.
It's worth noting that the app sometimes requires updating your graphics card drivers for stable operation. If you experience audio and video out of sync, try lowering the bitrate in the app settings.
Why might the Smart View app not see my TV?
Often, the problem lies in the Windows Firewall settings. You need to add the application to the exceptions list and allow access to the private network. Also, make sure UPnP is enabled on your router.
Configuring a media server to access the file system
For advanced users with large movie collections, the optimal solution would be to set up a full-fledged media serversThis will turn your computer into storage that the TV accesses like an external hard drive.
In Windows, this feature is called "Media Streaming." To activate it, open the Control Panel, find the appropriate section, and enable streaming. Then, in the TV's input source menu (the button) Source or Input) your computer will appear.
By accessing the "Media" section on your TV, you'll see your PC's folder structure. This allows you to navigate files directly from the remote, making it convenient for family viewing. Metadata, cover art, and movie descriptions are supported.

| Stability | High | Requires 5 GHz Wi-Fi |
| Control | From the TV remote control | Convenient for sofa viewing |
If standard Windows tools are not enough, you can install a third-party server, for example, Plex or JellyfinThey automatically download posters, sort series by season, and stream content with a beautiful interface.
☑️ Streaming Readiness Check
Troubleshooting connection and buffering issues
Even with proper setup, technical difficulties can arise. Most often, users encounter a problem where the TV simply doesn't see the computer in the list of available devices. This is a classic problem with network profiles.
Make sure the network your devices are connected to is set to "Private." Windows blocks detection on public networks. Also, make sure your antivirus or firewall isn't blocking the ports required for DLNA and Miracast.
If the video stutters or stops to buffer during playback, it means there is not enough bandwidth. 2.4 GHz band is often overloaded with neighboring routers, which causes interference.
⚠️ Note: To stream high-resolution video (4K HDR), it is highly recommended to use a router that supports the 5 GHz band or the Wi-Fi 6 standard.
It's also worth updating your TV's firmware. Manufacturers regularly release patches that improve compatibility with new versions of Windows and fix networking errors.
Alternative methods and browser broadcasting
If you're watching videos in a browser (such as YouTube, Vimeo, or online cinemas), you don't need to use system features. In a browser Google Chrome And Microsoft Edge There is a built-in Cast function.
Click the three dots in the upper-right corner of the browser, select "Save and Share" (or "Cast"), and find your TV. You can cast a specific tab or your entire screen. This even works on macOS.
Another option is to use technology AirPlay 2If you have a MacBook, many new Samsung TV models support AirPlay natively. Simply click the cast icon in the macOS or iOS player and select your TV.

Why can't my Samsung TV see my computer via Wi-Fi?
The most common issue is that the devices are connected to different router frequencies (2.4 GHz and 5 GHz) and isolated by the router's AP Isolation settings. Network discovery in Windows may also be disabled.
Is it possible to play PC games on TV via Wi-Fi?
Yes, using the "Screen Mirroring" feature or specialized software like Steam Link. However, for a comfortable gaming experience without input lag, a powerful router and close proximity to the devices are critical.
What video format is best for DLNA?
The most universal format is MP4 with the H.264 codec. MKV is also widely supported, but complex audio tracks (such as DTS) may not play without transcoding.
Does broadcasting reduce picture quality?
When using Miracast (screen mirroring), quality may be slightly reduced due to video stream compression. When using DLNA (file transfer), the original quality remains lossless.
